Acoustic standing wave technology combined with microtechnology opens up new areas for the development of advanced particle and cell separating microfluidic systems. This tutorial review outlines the fundamental work performed on continuous flow acoustic standing wave separation of particles in macro scale systems. The transition to the microchip format is further surveyed, where both fabrication

During the last years evaluation has been on the agenda as a part of the discourse in social work and social services in Sweden. This demand on evaluation and the value of the social work is connected to the tough economic situation in the municipalities and their growing responsibility for the social welfare services. At the same time there are strivings to improve the quality of social work and

The ABBI (Audio Bracelet for Blind Interaction) device is designed for visually impaired and blind children to wear on the wrist and produce sound based on the movement of the arm through space. The primary func- tion is to inform a child (or adult) about his/her own movements to aid spatial cognition rehabilitation. How- ever, the device could also be worn by friends and family and be used to inf

We performed ultrasonography on 32 athletes complaining of intense pain in a swollen and tender thigh or calf after a contusion or stretching trauma. The ultrasonogram was used to visualize the presence and size of a suspected hematoma. The findings included the following: 7 patients with a circumscribed, anechoic lesion compatible with a liquefied hematoma; 10 patients with a circumscribed lesion

Popular Abstract in Swedish Programvara spelar en allt viktigare roll i industriella produkter. Bilar, flygplan, telefoner, hemelektronik, kärnkraftverk m.m. innehåller alla programvara. När man utvecklar programvara blir det ofta fel i produkterna, fel som kan vara mycket allvarliga för funktion och säkerhet. Ett första steg i att minska dessa fel är att uppskatta hur många fel som finns i produkIn software engineering, the quality of software and in particular the software reliability has to be controlled and improved. Hence there is a need for measuring and controlling the number and appearance of software faults and failures. This thesis presents models for estimation of residual faults after inspections and a model for usage specifications which enables estimation of operational failu

Few cases of atrial fibrillation can be completely excused from the possibility of having some impact of potential importance in the aviation environment. The clinical pattern in paroxysmal disturbance is very wide and possible incapacitating phenomena are mainly haemodynamic. In contrast, chronic atrial fibrillation is mostly well-tolerated with only minimal haemodynamic effect, but there is a ri

Calls for more robust societal emergency management capacities have grown shriller as the range of societal vulnerabilities widens. The development of workable plans is recognised as one means to increase capacity. However, scepticism persists that plans serve any significant function in guiding organisational emergency management. Plans nevertheless remain a de facto requirement for most organisa

Today embedded system development is a complex task. To aid the engineers new methodologies and languages are emerging. During the development the system is modeled using different tools and languages. Transformations between the models are traditionally done manually. We investigate the automation of this process, specifically we are looking at automatic UML to SystemC transformation. In this pap

Popular Abstract in Swedish Att mäta kroppsställningar och rörelser under arbete Belastningsskador är vanliga och medför höga kostnader, både för de drabbade och för samhället. Kvinnor som arbetar med repetitivt arbete, t.ex. monteringsarbete och livsmedelshantering (fiskberedning och kycklingslakt), drabbas ofta, särskilt i nacke, axlar, armar och händer. De åtgärder som genomförts på arbetsplatWork-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. The present work shows, that available electrogoniometers are, with a sampling frequency of 20 Hz, feasible for measurin

A sequential Bayesian estimation algorithm for joint positioning and multipath mitigation in global navigation satellite systems is presented, with an underlying process model that is especially designed for dynamic user scenarios and dynamic channel conditions. In order to facilitate efficient integration into receivers it builds upon complexity reduction concepts that previously have been applie

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w

The goal of the paper is to present a distributed scheme to resolving a single path routing problem in multidomain networks. The global problem is formulated as a mixed-integer program (MIP) and approached by means of branch-and-price (B&P). Problems associated with a B&P tree nodes are decomposed using the Dantzig-Wolfe method to a set of domain subproblems coordinated by a single master

Popular Abstract in Swedish I mitt arbete som transplantationskoordinator på Kliniken för njurmedicin och transplantation på Universitetssjukhuset MAS i Malmö kommer jag i kontakt med många patienter som väntar på njurtransplantation. Det ingår i mitt arbete att informera dessa patienter inför uppsättning på väntelistan för njurtransplantation. En annan av mina arbetsuppgifter är att koordinera ocGreat efforts have been made to find solutions to the shortage of organs, such as extending the donor pool by accepting so-called marginal donors and development of transplantation of organs from animals (xenotransplantation, xt). Due to the scarcity of organs, there is a long tradition of prioritizing among patients on the waiting list for transplantation. Rules for allocation of organs have been

A pre-screening procedure with a number of candidate Human-Machine-Interaction solutions (visual, auditory and haptic) for the concept of Safe Speed and Safe Distance was carried out. Two groups of about 30 test persons participated in the two-phase test procedure. Eleven candidate visual displays for speed information and ten alternatives for distance warning as well as twelve auditory warning so
